[aprssig] KB8ZGL messaging woes update

If you are saying the message suddenly appeared in msg.cgi, there is  
no way that can happen, data is only added to findU in real time. If  
you are saying the message link on find.cgi suddenly appeared, that  
could be real. Doing a search to see if any messages are available for  
a call is rather time-intensive, because the message table is so  
large. Instead of performing this search for each of the tens of  
thousands of times a day find.cgi is hit, the system runs a script  
every 30 minutes that determines which calls have messages (and  
telemetry, weather data, etc.) and stores all that info in a compact  
and easily searched table. This table is what is ht with every cgi,  
but since it is small and kept in ram the search is very efficient.  
The price paid is when a new type of data is sent to or by a call, it  
will take up to 30 minutes before the find.cgi page shows a link to  
msg.cgi. However, the messages are viewable immediately with msg.cgi.

So, if the situation fits this scenario (no messages to pr from a call  
in 25 days, then messages sent but not link to msg.cgi on find.cgi),  
this is expected. If it is something else, you would need to provide  
more information before I could give you an explanation.
